Abstract: In this paper, more than 100 articles related to anode catalysts for the direct methanol fuel cell (DMFC) are reviewed, mainly focusing on the three most active areas: (1) progress in preparation methods of Pt–Ru catalysts with respect to activity improvement and utilization optimization; (2) preparation of novel carbon materials as catalyst supports to create a highly dispersed and stably supported catalysts; (3) exploration of new catalysts with a low noble metal content and non-noble metal elements through fast activity down-selection methods such as combinatorial methods. Suggested research and development (R&D) directions for new DMFC anode catalysis are also discussed.

Abstract: A status report on development of the direct methanol fuel cell (DMFC) and relevant fundamental and applied electrochemistry is the objective of this review paper. Emphasis is put on strategies and approaches rather than on individual results. The state-of-the-art in the fields of methodology, catalysis, catalyst characterization, polymer electrolytes as well as assessment and interpretation of cell and electrode performance is described. Today’s cell performances are regarded critically. Problems and successes are analyzed. Directions and novel approaches for further work are also suggested.

Abstract: Multiwalled carbon nanotube-supported Pt (Pt/MWNT) nanocomposites were prepared by both the aqueous solution reduction of a Pt salt (HCHO reduction) and the reduction of a Pt ion salt in ethylene glycol solution. For comparison, a Pt/XC-72 nanocomposite was also prepared by the EG method. The Pt/MWNT catalyst prepared by the EG method has a high and homogeneous dispersion of spherical Pt metal particles with a narrow particle-size distribution. TEM images show that the Pt particle size is in the range of 2-5 nm with a peak at 2.6 nm, which is consistent with 2.5 nm obtained from the XRD broadening calculation. Surface chemical modifications of MWNTs and water content in EG solvent are found to be the key factors in depositing Pt particles on MWNTs. In the case of the direct methanol fuel cell (DMFC) test, the Pt/MWNT catalyst prepared by EG reduction is slightly superior to the catalyst prepared by aqueous reduction and displays significantly higher performance than the Pt/XC-72 catalyst. These differences in catalytic performance between the MWNT-supported or the carbon black XC-72-supported catalysts are attributed to a greater dispersion of the supported Pt particles when the EG method is used, in contrast to aqueous HCHO reduction and to possible unique structural and higher electrical properties when contrasting MWNTs to carbon black XC-72 as a support.

Abstract: This article introduces the radical approach of applying alkaline anion-exchange membranes (AAEMs) to meet the current challenges with regards to direct methanol fuel cells (DMFCs). A review of the literature is presented with regards to the testing of fuel cells with alkaline membranes (fuelled with hydrogen or methanol) and also to candidate alkaline anion-exchange membranes for such an application. A brief review of the directly related patent literature is also included. Current and future research challenges are identified along with potential strategies to overcome them. Finally, the advantages and challenges with the direct electrochemical oxidation of alternative fuels are discussed, along with how the application of alkaline membranes in such fuel cells may assist in improving performance and fuel efficiency.
